Figure 17 is a modification of my invention.

My new and improved hose reel mechanism has a drum or reel I rotatablein a winding direction to wind a hose II thereon and rotatable in anunwinding direction to permit unwinding of the hose therefrom. A drivemeans I2 rotates this drum in the winding direction and resists rotationof the drum in the unwinding direction. I have employed a Valve means I3which is responsive to a change of rotation of the drum to control thedrive means I2. In Figure 1 of my drawings I diagrammatically illustratethe component parts of my hose reel mechanism. It is understood that mydrive means may be an electric motor, an air motor or any other devicewhich will rotate the drum in one direction and resist rotation of thedrum in the opposite direction. The valve means I3 which is responsiveto change of rotation, is defined in its broad aspect to include airvalve, electric switches or such equipment as is necessary to controlthe operation of the drive means I2. I also use the term hosedescriptively and intend that its meaning shall include a rope, cable,electric wire or any other flexible member which may be wound on a spoolor drum.4

The drum or reel I0 is carried by a drive shaft I4 extending from thedrive means I2, as is diagrammatically illustrated in Figure 1. Aflywheel I5 is journalled in the drum at a distance from the centerthereof. The flywheel is carried around the drive shaft I4 by the drum|0 and ls also rotated on its own'axis. A ring gear I6 is angulai lymovable on a support collar II extendlng from the drive means I2. Thering gear I6 has a valve operating cam surface I8. The valve means I3has a valve stem I8 engaging this cam surface I8. When the ring gear I6is angularly moved from the position as indicated in Figure l to theposition as indicated in Figure 2, the valve stem I9 and the valveoperating cam surface I8 co-operate to operate the valve means |3. Apinion gear 20 engages the teeth of the ring gear I6 and is adapted totravel thereabout. A clutch mechanism 2| interconnects this pinion gear20 and the flywheel I5 which is journalled in the drum I0. Rotation ofthe drum I0'in either direction causes the pinion gear 20 to travel atleast partially around the ring gear I 6 to spin the ilywheel I5. Achange of rotation or deceleration of the drum causes the flywheel torespond to its own inertial rotation to continue turning the pinion gear20 and thereby angularly move the ring gear I6. The lclutch mechanism 2|which interconnects the flywheel I5 and the pinion gear 20 permits agradual slowing down of the inertial rotation of the flywheel to preventdamage to the gear teeth or other parts of my hose reel mechanism.

The drum I0 as well as the motive and valve control parts therefore maybe housed in a housing 25 having an opening 26 therein through which thehose may be pulled. The drum I0 may be constructed of any convenientdesign which will readily permit Winding and unwinding of a hosethereon. This drum I0 has a bearing portion 30 in which the flywheel I5is journalled. The drum |Il is adapted to be carried by the drive shaftI4 and has a center portion 3| fastened to the drive shaft I4. Thebearing portion 30 ls disposed from the center portion 3| of the drum, adistance substantially equal to the radius of the ring gear I6. Acounterweight 32 is fastened by bolts, or other suitable means, to thedrum I0. This counterweight 32 is disposed on the opposite side of thecenter portion 3| from the bearing portion 3i) to balance the drum. Thecounterweight is substantially of the same weight as the weight of theflywheel I5.

A pinion 33 extends through the bearing portion 30 to support theflywheel I5. This pinion shaft 33 has the pinion gear 20 fastened on oneend thereof and the clutch mechanism 2| onrthe other end thereof.Although other suitable clutch mechanisms may be used, I desire touse-a. sleeve 34 pinned to the pinion shaft 33. This sleeve 34 has aflange clutch surface 36 extending thereabout to engage a clutch surface31 of the flywheel I5. The flange clutch surface V36 on the sleeve 34 isdisposed on a plane substantially parallel to the plane of the flywheelI5. A washer 38 is loosely fitted over the sleeve 34 and ls urged towardthe flange clutch surface 36 by a clutch spring 39. An inner portion 40of the flywheel 5, which has the clutch surface 31 on the side thereof,is disposed between the flange clutch surface 36 and the washer 38. Aspring fastener 4I is fastened to the sleeve 34 and extends outwardlythereof. The spring 39 pushes against this spring fastener 4| to urgethe washer 38 toward the flange clutch surface 36 thereby clutchinglyconnecting the flywheel I5 to the pinion gear 20.

The hose is connected to ,'a source of air or fluid under pressure bymeans of a swivel joint 43 which is located in the drive shaft I4. Thedrive shaft has a hole 45 bored in the end with a countersunk hole 46extending from the bottom of the hole 45. These holes, 45 and 46,provide a shoulder 41 therebetween. A smaller countersunk hole 48extending from the bottom of the countersunk hole' 46 co-operatestherewith to provide a shoulder 49. An air passage 50 is drilled throughthe shaft into the smaller countersunk hole 48. An air connection means5| fastened to the end of the hose Il is threaded into this air passage50. A tubular member 52 carried by an air supply line 53 extends intothe smaller countersunk hole 48. Packing 54 and snap rings 55 are fittedinto these holes 45 and 46 to prevent escape of air from the smallercountersunk hole 48. The snap rings 55 press the packing 54 against theshoulders to insure a sealed swivel joint Which will permit rotation ofthe drum I0 with respect ftolthe' air 'supply '1ine53 withoutflos'ingmr'pressure inthe hose II. f

I have housed thev hosereel mechanism in the housing 25 having opening`2.6 therein through which the'.hose is pulled. .,In

4these drawings' have schematically"illustrated the valve means whichcontrols the motor. .@In Figure '7, thehose is completely wound onthedrum and the valve means I3 is closed,`thus the .motor is de-energized.Figure 8 illustratesthe relationship between the valve .stem I9 'andthecam surface IB when the `motor is def-'energized and when all the partsin my -hose reel mecha'- 'nlsm` are at a standstill.v Figure 9 alsoillustrates in cross-section, the'position of the component parts of myhosev reel mechanismat this time.

This energization of the motor or drive means I2 will operate throughthe distributor valve 85 to operate the motor. and thus cause it torotate the drum I in a winding direction. The

'rotation of the drum II) in this winding direction is illustrated inFigure 14. The arrow 91 in Figure 14 represents the winding direction.Again the flywheel I5 is carried about the ring gear I6 thus causing thepinion gear 2U to travel about the ring gear and spin the flywheel. Therotation of the drum I0 in the winding direction causes the flywheel I5to spin in the direction illustrated by the arrow 9B in Figure 14. Ifthe operator let go of the hose at this time, it would be completelyreeled onto the drum; however, should the operator wish to use the hosewithout having back tension or forces tending to wind the hose on it, hesimply kholds the hose tight for a short period of time.

After the drum has rotated in the winding direction sufficiently to windslack in the hose and to spin the flywheel in the direction illustratedby the arrow 98, the drum comes to rest. I have illustrated thisposition in Figure 14 by the solid lines illustrating the flywheel andother component parts of my hose reel mechanism. It is to be understoodthat although I have illustrated the drum as rotating only aboutone-fourth turn in the winding direction between the Figures 11 and 14,it may rotate any number of turns or any portion of a turn before beingbrought to the stop position illustrated in Figure 14.

Immediately after the drum has stopped rotating in the windingdirection, the inertia of the flywheel causes it to continue to spin andthereby angularly move the ring gear I6 to the position as illustratedin the Figure 15. Since the flywheel is rotating in the oppositedirection from the unwinding rotation of the drum to that in which itrotates from the winding rotation of the drum, the ring gear I6 is alsomoved angularly in the opposite direction. The valve stem I5 and thevalve operating cam surface I8 on the ring gear co-operate to permit thevalve means I3 to close to de-energize the motor or drive means I2.After the motor has been deenergized the hose II may be freely usedWithout having any forces exerted to wind it onto the drum. I havediscovered that many pounds of air pressure may be forced through thehose in my hose reel mechanism, without causing any forces tending torewind the hose to be exerted upon it.

When the operator is through using the hose, he simply has to pull thehose a short distance to rotate the drum in the unwinding direction. Aportion of a rotation of the drum in the unwinding direction isgenerally sufficient to spin the flywheel. The flywheel, because of itsinertia, will operate as between Figures 'l and 10 to open the valvemeans I3 and cause energization of the motor or drive means I2 to rewindthe hose. Figure 16 illustrates the connection of a spring 99 betweenthe hose and the drive shaft I4 which carries the drum. This spring 99,normally compressed, maintains a short part of the hose wound onto thedrum. Thus, should the operator accidentally unwind the hose clear tothe end, the spring will insure a means of rotating the drum 8 in a veryshort unwinding direction to operate the flywheel to start the motor.

In my description of operation of my new and improved hose reelmechanism, I have completely stopped the drum from'rotating in eitherdirection to better illustrate the operating of the valve means whichresponds to the inertial movement of the flywheel. It is understood thata mere change of rotation will cause the flywheel to operate the valvemeans. This change of rotation of the drum in either the winding orunwinding direction may be a complete reversal of direction of rotationor a change in the speed of rotation. When the drum is rotated at auniform speed, the inertial mass of the flywheel is uniform; however, ifthe drum suddenly decelerates or stops the inertial mass of the flywheelwill cause it to continue spinning and thus angularly rotate the ringgear.

In Figure 17 of my drawings, I illustrate a modification of mymechanism. In this modification the ring gear is fastened to the drum orreel and rotates therewith. An arm |00 having a flywheel journalled inthe end thereof, is pivotally supported to operate the valve means. Thepinion gear 20 fastened to the flywheel I5 spins the flywheel I5 whenthe ring gear I6' is rotated by the drum. A change of rotation of thedrum causes the pinion gear to travel partly about the ring gear. Whenthe pinion gear is caused to travel about the ring gear by the inertialmass of the flywheel, the arm is pivotally moved to operate the valvemeans.

Although I have described my invention in its preferred form with acertain degree of particularity, it is understood that the presentdisclosure of the preferred form has been made only by way of exampleand that numerous changes in the details of construction and thecombination and arrangement of parts may be resorted to withoutdeparting from the spirit and the scope of the invention as hereinafterclaimed.
